Intended Outcomes for the courseUpon successful completion of this course the student shall have satisfactorily accomplished the goals and objectives listed in the Course Content and Outcome Guides, including;
- Demonstrate competency when dimensioning all types of technical mechanical drawings using ANSI/ASME Standards.
- Demonstrate a through understanding of tolerancing practices used to develop fits and limits when designing mating parts.
- Understand surface finishing concepts and correctly use surface finish symbols when producing mechanical drawings.
- Understand and use the American National Standard Limits and Fits tables.
Course Activities and Design
This course will be presented by means of lecture presentations and coordinated laboratory exercises. Lectures are supplemented with selected reading assignments. Individualized instruction will be provided while the student is working on lab projects. This course utilizes freehand sketching techniques learned in previous drafting classes. The majority of assignments will be completed using the AutoCAD 2-D format.
Outcome Assessment StrategiesEvaluation procedures and grading criteria will be discussed during the first class meeting. Individual and classroom discussions, completed assignments, attendance and classroom participation. exams, quizzes, and worksheets may be used to assess outcomes.
